Moving microfluidics from the lab bench to the factory floor

Microfluidic devices have the potential to be fast, cheap and portable diagnostic tools. But for the most part, the technology hasn’t yet made it to the marketplace. While scientists have made successful prototypes in the laboratory, microfluidic devices — particularly for clinical use — have yet to be manufactured on a wider scale.

Bentley Donates Software to Engineers Without Borders - USA in Support of Volunteers’ Important Work Sustaining Infrastructure

On behalf of all of our chapter members, I thank Bentley for this generous gift!”

Innovative 3-D designs from an MIT team can more than double the solar power generated from a given area

Now, a team of MIT researchers has come up with a very different approach: building cubes or towers that extend the solar cells upward in three-dimensional configurations. Amazingly, the results from the structures they’ve tested show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.

More than half of all cancer is preventable

In a review article published in Science Translational Medicine March 28, the investigators outline obstacles they say stand in the way of making a huge dent in the cancer burden in the United States and around the world.

Bentley Systems’ Faraz Ravi Named Chairman of ASTM International Committee on 3D Imaging Systems

Bentley’s commitment to point clouds was first underscored in 2009 with its incorporation of the Vortex engine in its MicroStation information modeling environment. This past November, concurrent with its Pointools acquisition announcement, Bentley previewed advanced point cloud processing innovations in its forthcoming Bentley Descartes V8i (SELECTseries 3) release that speed point cloud workflows and reduce costs.

CDC estimates 1 in 88 children in United States has been identified as having an autism spectrum disorder

The number of children identified with ASDs ranged from 1 in 210 children in Alabama to 1 in 47 children in Utah. The largest increases were among Hispanic and black children.

Report to the nation finds continuing declines in cancer death rates since the early 1990s

The report is co–authored by researchers from the Centers for Disease Control and Prevention, the North American Association of Central Cancer Registries, the National Cancer Institute, and the American Cancer Society. It appears early online in the journal CANCER, and will appear in print in the May issue.

Prevalence of Autism Spectrum Disorders

The American Academy of Pediatrics (AAP) understands how concerning these numbers are to parents. Pediatricians know parents want answers about what causes autism, and so do the AAP and the pediatricians who care for children with autism every day. Some of the increase may be due to how children are diagnosed and treated in their communities. There also may be a true rise in incidence. To understand more, the scientific community must accelerate the research to understand what is putting children at risk for this disorder.

Understanding factors that promote smoking key to improving cessation rates

In a new study published in the American Journal of Public Health, Jason Q. Purnell, PhD, assistant professor at the Brown School at Washington University in St. Louis, looked at how perceived discrimination influences smoking rates among these groups.

Investigational targeted drug induces responses in aggressive lymphomas

Lymphomas are the fifth most common form of cancer. They are caused by an abnormal proliferation of white blood cells, can occur at any age, and are often marked by lymph nodes that are larger than normal, fever, and weight loss. Diffuse large B-cell lymphomas (DLBCL), which were studied in this trial, are aggressive cancers that grow rapidly and represent 30 percent to 40 percent of newly diagnosed lymphomas. DLBCL originates from B cells, which play a crucial role in the body’s immune response.

Can the Supreme Court survive a health-care decision?

“The Supreme Court may make the ‘wrong’ decisions on health care and other issues this spring. But as a widely legitimate institution, the court will be able to make these decisions with impunity,” writes James L. Gibson, PhD, in Miller-McCune. “As it stands today, the U.S. Supreme Court is in fact nearly invincible. For better or for worse.”

New study shows liver cancer patients are less likely to die on wait list than candidates without cancer

With the scarcity of available livers for transplantation, it is imperative that the prioritization criteria ensure that the candidates who are at the greatest risk of dying from the disease be the first ones to receive a life-saving organ," said lead author David Goldberg, MD, an instructor in the department of Gastroenterology. "Our study compared the morality risk for patients with HCC to those with similar scores, but without liver cancer. What we found is that ultimately, the process used to determine transplant priority is making it so that these HCC patients are receiving healthy livers first, when in actuality, they are less likely to die while waiting for a new organ. This is an issue of utmost importance, because nearly 2,000 patients die each year waiting for a new liver on the transplant waitlist, while 25 to 30 percent of transplants are performed in patients with HCC."
